A levitating light bulb uses wireless energy.

Everyone remembers the moment in the end of Back to the Future when you see the first realistic flying car from the year 2015, which operated on fuel from organic compost. We are only 5 years away from that landmark year, and yet, while people look to find alternative fuels. The levitation aspect is not quite there yet — or is it?

Hack n’ Mod points us to a series of controlled levitation experiments utilizing magnets and sensors:

The magnetic levitation bulb also uses wireless energy transfer to not only light it up but also make it ‘magically’ float in mid air. Two magnets and two electromagnets keep the light bulb afloat. The light bulb is attached to a Hall sensor and magnet that settles the voltage as the magnetic field changes. The bulb is then illuminated by the inductive current from the magnetic field.

Watch a demo below:
